Letters Patent No. 110,134, dated December 13, 1870.

IMPRovi-:MENT iN coTToN-sEED HnLLEns.v

The Schedule referred to in these Letters Patent'and making part et' the same.

extending nearly in a radial line from a point near the center of the head, to its outer edge, and project- -ing ou each side of the head suciently to catch and cut the cotton-seeds, as hereinafter described.

The shell is constructed in any proper manner and form, so as to inclosc the revolving cutter-head, with openings upon each-side of the shell, to which hoppers are fitted, so as to supply the cotton-seed into the shell, against each side ot the cutter-head.

A suitable opening is also made in the edge of the opposite part of the shell, for the discharge of the hnlled seeds by the centrifugal action of the revolving head.

At the bottom of the hoppers, upon each side of theshell, adjustable knives are fixed, extending through the side of the shell, and meeting the cutters in the revolving head at a proper' angle, so that the seeds are cut by the knivesand cutters in like manner as the cutting edges of the ordinary shears.

Upon each side of the interior of theshell, between vthe above-described knives and the opening through which the seeds are discharged, are fiat radial bars or projections, for the purpose of more eii'ectually separating-the kernels previous to the discharge of the seeds.

In the accompanying drawingsy Figure 1 is'a side view of the machine, showing the driving-shaft I,'adapte'd either for hand or other power. f

Figure 2 is va. view oQone of the exteriorsides of the shell A, showing the hopper' G in position, and.

the screws P P, by which thc two parts of the shell are secured together.

.Figures 3 and 4 are views of the interior of the I left and right parts of the sheli,showiug the position of the radial bars S S S S S S. and the knives D D.

Figure 5 is a sectional view of the cutter-head B, and. of one side 4of the shell A.

Figure 6 is a side view of the cutter-head', showing the cutters C C C in position.

The figures upon the right and left-of fig. 5 are side and sectional. views of -the cnt-ters C and of the knives D.

A is the shell or case of the machine, substantially constructed in two parts, secured togetherby the screws P P.

B is the cuttcrdiead, which may be made of any diameter, and should be of' suliicientthiclniess to rmly hold the cutters. l

C C C are the cutters, which should be wide enough to project on each side ot' the head sufficiently toont thcseeds, and may be made V-shaped at the inner end o, to secure them from any lateral movement,

and by means of the screws l E F they are tirinly and innnovably fixed in the head, their outer ends being set forward ot radii ot' the head, as shown in tig. 6, so as to facilitate the cutting ofthe seeds.

The outer ends of' the cutters 'also projectbeyond the edge ofthe head, so as to keep the shell clear.

D D are adjustable knives, placed in each side of the shell, and are securely clamped between suitable projections from each side of the shell, and the base ot' the hoppers, which are pressed tightly upon the knives by' the screws N N, iig. 1.

E E are set-screws, by which the knives are adj usted close to the revolving cut-ters.

G G are vthe hoppers, which are pivoted to the shell by the screws L L, and when clamped upon the knives by the screws N N they arc iirinly held to thc shell A.

H is the driving-pulley, and I the shaft, passing through suitable bearings in the shell, by which motion is given to the cutter-head.

I claim as my invention- 1. .The cutter-head B, provided with one or more double-edged cutters C, fastened by the vshaped and described, for the purposes set forth.

2. The adjustable knives D D, forming the bottom l of the hoppers G G, in combination with the cut-terhead B, when constructed and arranged substantially as herein shown and-described, for the. purposes set forth.

3. The combination of the shell A, provided with.A
